Aonix ObjectAda running under Windows can produce DOS executables!
I suspect that one can have Ada take control of Windows CE.

Thanks for the reply.
There are probably more than 3 options here. I know of one commercial
development that is using x86 embedded CPU with DOS to make a hand-held
Automotive Test instrument . They are using C & C++.
Since Ada is not available that was not even a factor. This is an
upgrade/conversion from an earlier CPU that is no longer available.
See my comments below and others can chime in.

If you're not using a disk then that is not a problem. Even a Ram disk or
Flash can usually deal with short names. I'm talking embedded Single Board
Computer (SBC) -- may or may not need "Real-Time"

Wince (ugh!) is Not Real-Time and is a CLOSED OS. Ada for the Palm Pilot !
That is an idea!

Linux and Ada are a good fit here as well. Linux has a Real-Time Kernel
option and word is ACT is working with other folk to integrate that with the
Ada Tasking Model. The FSU thread model may do all that most folk need.

Not too familiar with these but bindings and libraries for this are
available. Embedded systems may not need to deal with this at this level.
